Microsoft Clarity #1 in session replay tools · input masking you are not allowed to switch off, free, with no traffic limit — and a business model worth understanding.
88 /100 verdict the only tool here where a careless install is still a safe install, because the masking is not yours to disable.

PostHog #3 in session replay tools · masks all inputs by default, hosts in the eu on every plan including free, and you can self-host the mit core.
